This is a tool for generate version by git revsisions. It base on docker and isolated from source codes. So it can work with any kinds of code, such as Java, Node, Python.

Copy GitVersion.yml.sample to your code base at root folder. And rename to GitVersion.yml.

The GitVersion.yml determine how the version increase and especilly the next-version.

The sample of Jenkinsfile

stage('Prepare') {
      steps {
        sh "sh gitversion/genGitversion.sh ${WORKSPACE}"
        stash(includes: '.gitversion.json', name: 'gitversion')
      }
    }

Above steps will generate a .gitversion.json file and stashs into artifact repo of Jenkins

Save the .gitversion.json in the build process for store the version information into application packages or image

stage('Build Docker Image') {
      steps {
        unstash 'build'
        unstash 'gitversion'
        sh "... build ..."
      }
    }

For example: use gitversion for tagging the docker image

stage('Push to Repo') {
      environment {
        GIT_VERSION = sh (
          script:"sh gitversion/showGitversion.sh ${WORKSPACE}",
          returnStdout: true
        ).trim()
      }
      steps {
        sh "docker tag app:latest app:${env.GIT_VERSION}"
        sh "docker push app:${env.GIT_VERSION}"
      }
    }
